Roberts filmed her first-hand view for Hollaback!, a non-profit organization that raises awareness about street harassment.

The recording of Roberts, an actress, is now being used by the organization as a PSA titled, "10 Hours of Walking in NYC as a Woman."

“I wanted to give it to guys who would maybe consider whistling at a girl,” said Rob Bliss, the owner of his own creative firm who reached out to Hollaback! with the idea of creating the PSA.

“To see things from the other side and to really feel for the first time, going through this every day, I feel kind of sick,” said Bliss, who captured the catcalling with a GoPro camera hidden on his back while he walked in front of Roberts.

Viewers of the PSA have responded with comments online like, “No woman should ever have to experience this,” and, “All you men should be ashamed of yourself.”
